SPECIFICATION vforming part of Letters Patent No. 781,020, dated January31, 1905. u

` i Application filed February 28, 1904. Serial No. 194,745.

To LUM/hom, t may concern.'

Be it known that I, W" ELLES MORTIMER PAR- TRIDGE, of Peabody, county ofEssex, State of Massachusetts, have invented an Improvement inGas-Stoves, of which the following description, in connection with theaccompanying drawings, is a specification, like characters on thedrawings representing like parts.

This invention relates to gas-stoves or appliances'especially adapted tobeplaced in an ordinary kitchen stove or range having an oblong oroval-shaped fire-pot without permanently altering said stove or range,and is intended 'as an improvement upon the gas-stove or appliance shownin my application for Letters Patent, Serial No. 747,474, datedDeceniber 22, i903. Y

My present invention has for its object to improve the construction oflthe appliance to the end that it may be' more easily constructed andadapted to fit iire-pots of different sizes and that the burners may besupported at vregular distances from the side walls of thedifferently-sized {ire-pots' and a pilot `light y bodying thisinvention. Fig. 2 is a longitudinal vertical section of the gas-stove,taken on the dotted line 2 2, Fig. 1. Fig. 3 is a transverse verticalsection of the stove, taken on the dotted line 3 3, Fig. 2. Fig. 4 is aplan view of one of the burners. Fig. 5 is a detail showing in verticalsection three burners and one of the upright supports for the topburner.

Iwater coil or front and the side wall of the iire-pot, respectively,that the burner shall occupy. Fig. 8 is a sectional detail of theuppermost pilot-light. Fig. 9 is a sectional detail of the pilot-lightfor the two oppositely-disi posed side burners. Fig. 10'is a verticalsecand the gas-supply nozzle. Fig. 11 is a detail showing the means foradjusting the air-supply. Fig. 12 is a sectional detail showing thelowermost pilot-light. Fig. 13 is a modification showing a diiferentwayof closing the ends of the burners. Fig. 14 is adetail showing theseveral burners made as half-castings bolted together. Figs. l5 and 16are details of portions of the burners made as half-castings. Fig. 17 isa plan view of the burner, showing a modified form of top burner andshowing means for delivering gas to each side burner separately. Fig. 18is a vertical section of the'side burners, taken on the dotted line 1818, Fig. 17. Fig. 19 is a perspective view of a water-front which may beemployed. Fig. 20 is a longitudinal vertical section oi' the water-frontshown in Fig. 19, taken on the dotted line 20 20. Fig. 21 is atransverse vertical section of the water-front shown in Fig. 19, takenon the dotted 'line 21 21. Fig. 22 is a detail of one of the iittings ofthe double coil of the water-front.

c@ represents a gas-supply pipe having at one `side a plurality ofopenings'into which the shut-off valves a', a2, as, and a4 are screwed,each shut-ofi valve having lsecured to its case a nozzle a5, (see Fig.10,) which projects into i the enlarged end b of a pipe which deliversthe air and gas to the burners, four such deliverypipes 62, b3, and b4being herein shown. The enlarged end Z2 of each delivery-pipe is madeconical and forms a mixing-chamber, and upon the outer end oi' eachconical end portion I) two plates are placed, which are disposed oneupon the other, one of said plates, as c, being rigidlysecured to theend portion I) and the other, as c', having a marginal lip or flangeformedion! it, lwhich overlies and loosely engages thefplate c and isthereby free to revolve on said plate c.- Both plates c and 'c' haveseveral circular or other shaped holes through them, and as theoutermost plate c' is turned relative to the iiXed plate c air-inlets ofgreater oi' less dimensions will be provided.

A pair of burners are provided at the top of the appliance, whichconsist of a horizontallydisposed tubular casting al', havingsemicircular end portions', and a pair of parallel side portion.

portions provided with transverse walls 672, lo-

cated at points intermediate therein to thereby form two separatetubular compartments, and jet-orifices 67 are provided along the uppersurface of." the semicircular end portion and along a portion of theside portions, as best shown in Fig. '1. Two tubular transverse portions675 CZ are formed integral with the casting 07 near the middle, whichrespectively connect with the tubular compartments Z3 C74. A verticalpipe e leads to the transverse portion d5, the upper end of which isshouldered to provide a reduced neck c or end portion which is adaptedto fit into a tubular projection or boss e2 on the transverse portion,and a setscrew e3 is provided for holding t-he pipe c in any adjustedposition relative to the transverse The lower end of the vertical pipe ehas fitted into it the reduced neck or eXtension e4, formed on ahorizontal pipe e5, being held in place by a set-screw e, therebyproviding for vertical adjustment of the top-burnn ers, and the pipe b2is fitted into the opposite or outer end of said horizontal pipe e5,being held in place by a set-screw @7, thereby providingJr`or\horizontal adjustment of the enlarged end portion ci. The pipes e5and e deliver the air and gas directly to the transverse tubular portion675 and consequently to the tubular compartment (Z3. A similar Verticalpipe f leads to the transverse portion CZ, the upper end of which isshouldered to provide a reducedneck or end portion which is adapted tofit into a tubular projection or bossjl2 on the transverse portion, anda set-screw f3 is provided for holding the pipe f in any adjustedposition relative to the transverse portion. The lower end of thevertical pipe f has fitted into it a reduced neck or extension ft,formed on the horizontal pipe f5, being held in place by a set-screW-f,thereby providing for vertical adjustment of the top burners, and a pipe723 is fitted into the opposite or outer end of said horizontal pipe f5,being held in place by a set-screWf7, thereby providing for horizontaladjustment of the enlarged end portion b. The pipes f5 and f deliver theair and gas directly to the transverse tubular portion d, andconsequently to the tubular compartment di. Adjustment of the pipes canbe readily made by simply loosening the set-screws and moving the parts,whereas in the application above referred to, showing screw adjustments,much difiiculty has been encountered in adjusting the parts, as theseveral pipes had to be adjusted practically at the same time and thedistance between the top burners d and the stove-lids remained aconstant after the appliance was once installed, thus giving no chanceto adjust the burners according to the draft, so as to get perfectcombustion and maximum heat from the burners.

The side burner g consists of a tubular casting integrally closed at itsends or plugged, as shown 1n Fig. 13, and having a row or' jetorificesalong one side, and said casting has formed on it a tubular projectionor boss into which is fitted a vertical pipe y, which is held securelytherein by a set-screw (1. The vertical pipe g2 has fitted onto it orformed integrally with it a short horizontal pipe g4, into which isfitted a delivery-pipe 7;', which is formed with an enlarged end portion7). r[`he burner g is thus vertically and horizontally adjusted. Theburner r/ has formed integral with it a plurality ot` slotted ears Q20,which receive the supports for the burner in an adjustable manner,whereby the burner may be fitted to fire-pots of different widths. Asthe jet-orifices are located at the side of the burner, it is importantthat the burner be held a short distance away from the water-front forthe latter to receive the maximum amount of heat from the lateralgas-jets, and therefore I have provided the burner withlaterallyprojecting lugs (/4", which are shown in Fig. 6 as short screwsscrewed into holes in the burner, and in Fig. 7 I have shown said lugsor projections formed integral with the burner. I may provide theburners with lugs of either form and may employ as many lugs as desired.

The water-front herein shown consists of a double coil of pipe w, (seeFigs. 3 and 19 to 22,) which is connected at the ends by suitabletittings w with the inlet and outlet pipes, and said coil of pipe iscontained within or inclosed by a jacket or casing mi, which is open atthe bottom, and one side wall of said jacket or casing has anoutwardly-projecting` lip w3, which extends over the side burner f/ andwhich directs the heat to the coil of pipe. The jacket or casing hasholes fw" at the top. The jacket or casing may be covered wholly orpartially with asbestos sheeting.

The burners 7L, though two in number, are connected together so as toreally constitute a single burner and are located at the side of thefire-pot opposite the burner (l, so as to heat the oven, and saidburners each consist of a tubular casting closed at the ends integrallyor with plugs and constructed substantially the same as the burner g,each having a plurality of slotted ears 7L'. Each burner 71. has atubular projection or boss 71,2, into which is fitted a short verticalpipe 75, said short pipe being held therein by set-screws 71., and ahorizontal pipe 7L is provided, having a tubular projection or bossabove and below, into which said short vertical pipes are also fitted,being held therein by set-screws 7a, and said horizontal pipe has fittedinto its inner or front end a delivery-pipe 724, which is held thereinby a set-screw. rlhe air and gas are thus delivered to both burners 7L7L. As these burners are adapted to be held at the proper distance fromthe oven-wall of the fire-pot to heat the oven, they also havejet-orifices at the side and are provided with latcrally-projecting lugs71.7.

As supports for the several burners two IOO ITO

therein by a set-screw 254.

at right angles near its lower end, (see Figs. 3-

stands m n are provided, 'each consisting of a base adapted to rest onthe bottom of the ashpit and an upright bar rising from it,screwthreaded for a portion of its length and made of a diameter to passfreely through the slots in the ears on the burners, and nuts m n areplaced on said uprights above and below said ears. these stands, beingadjustablethereon vertically and also horizontally. Upright bars-0, twoin number, are located between the burner g and the uppermost burner 7L;which vare screw-threaded at each end, and the lower ends of said barspass through the slots in the ears on said burners and have placedthereon suitable nuts 0 above and below said ears, and the upper ends ofsaid bars pass through holes in the ears 02 on the uppermost burner, andnuts 03 are placed on said bar above and below said ears. The upper endsof the bars o are slotted to receive a screw-driver. By

4means of the upright bars 0 the uppermost burner is supported in anelevated position and is also independently adjustable to differentelevations, so as to bring the top gas-jets to the proper distance fromthe top of the range.

The pilot lights or burners', which are pirovidedfor the severalburners, are constructed as follows: t represents a horizontal pipewhich leads from' the gas-supply pipe a and has connected in it aby-pass valve t.' of any usual or lsuitable construction. A verticalpipe t2 has formed in it a horizontal tubular extension t3, which isadapted to receive the end of the pipe ,'which latter is securely heldand 12,) and the end of said pipe is closed except for a small hole orjet-orifice 5, for the gas.

rIhe lower end of the pipe t2 is directed toward and terminates near thevertical wall of the lire-pot above the lower burner 7L, and the gaswhich rises from said lower burner 71, crosses the path of the flameissuing from the jet-oriiices 15, and hence becomes ignited. 4 The lowerend of the pipe 152, having the jet-orifices t5, therefore serves as thepilot light or burner for the lower burner it. The upper end of the pipet2 has iitted into it a short pipe t6, which is held securely therein bya set-screw t7, and the upper end of said pipe t is iitted into thelower end of a vertical pipe t8, which is formed or provided with twotubular projections t t1", which extend in opposite ways, each of saidprojections having a closed end eliicept for a small hole orjet-orifice, as .1512

jet-orifices, serve as pilot lights or burners for the upper burner 71,and the'burner g and are directed toward the'oppositeside walls of thefire-pot just above said burners, and the'gas issuing from said burners/t and g crosses the path of the flames issuing from the pilot lights orburners t9 151 and is thereby ignited.

The burners g /t L` are supported by' The pipe t2 is bent The tubularprojections t tw, having the Into the upper end ofthe pipe t8 'a pipe tis tted, which is held securely therein by a setscrew, and a cap 1515(see Figs. 3 and 8) is e screwed onto the upper end of said vpipe t,which is formed or provided with two jetorices t1, leading in oppositeways, slanting l upward and outward. The kupper end of the pipe tterminates between the parallel side bars of the uppermost burner and atan-elevation, whereby the cap 15 occupies a position below the top ofsaid burner in order that the lighted jets of gas issuing therefromshall not be extinguished by the products ofl combustion from the burnerg as said products pass over top burners d, and theame issuing from thejet-orifices t1 passes across the top of said uppermost burners, beingdirected toward the jet-orifices of said burners, as shown in Fig. 1, sothat the gas issuing from the jet-- orifices of said burners-will beignited. By constructing the pilot lights or burners in this v manner itwill be seen that thesame are vertically and vhorizontally adjustablethroughout, so as to be moved into relatively correct positions for useinconnection with the several burners. l

Herein many of the parts are referred to as pipes; but I desire toinclude within the meaning of said term any form of tubular casting.

Instead of making the burners as cored castings they may be made ashalf-castings, as shown in Figs. 14:, 15, and 16, the'parts being boltedtogether and cement interposed between them, if desired. The top burnerZ may be made as a casting having the jet-ori- {ices arranged inelliptical form, as represented in Fig. 17, and in such event thetransverse IOO jet-orifices may be made as separate burners,

as shown in Figsfl? and 18,each having a separate delivery-pipe leadingto it.
